Sunsynk 12kW three-phase hybrid inverter

The SUN-12.0-3PH is Sunsynk's 12kW three-phase Classic hybrid inverter, supplied with WiFi included. It is the unit to spec when the supply is three-phase: workshops, farms and light commercial premises where a single-phase hybrid is not an option.

Description

Three-phase hybrid jobs often force a step up to a high-voltage battery platform. The Classic 12kW takes the other route: one unit on the three-phase board with the same 48Vdc battery bus as the rest of the Classic range, so the low-voltage packs and cable sets a Sunsynk installer already carries stay in play. WiFi is included, which removes an accessory line from the order. For firms that fit Sunsynk on domestic work and want the commercial and farm jobs on the same brand, this is the unit that keeps the parts bin common.

What it pairs with

On the metering side, pair it with the Sunsynk Eastron three-phase digital meter (SUN-METER-E-3P). For storage, the Classic range runs a 48Vdc battery bus, so look at Sunsynk's 5.32kWh IP65 batteries such as the W5.3, wired with the Sunsynk long battery-to-inverter cable set. Battery counts and revisions vary, so confirm the exact pairing against Sunsynk's current compatibility list before you quote.

This is the three-phase Classic model, so it needs a three-phase supply; single-phase premises take the 12kW single-phase version (SUN-12.0-1PH) instead. Its battery connection is 48Vdc, which places it in the low-voltage Classic ecosystem rather than the HV series. For anything this page can't settle, ask the trade desk before ordering or consult a competent installer.

FAQ

Sunsynk SUN-12.0-3PH buying questions

The price shown on this page is the ex-VAT trade price, and VAT at 20% is added on the invoice. It does not move with volume: one inverter for a single job costs the same per unit as a batch for the fitting schedule, with no minimum order and no spend tiers to qualify for.
It travels by parcel courier from UK stock. As an inverter without batteries it carries no dangerous-goods classification, so there is no pallet booking or kerbside handling to arrange at your end. Delivery in 3–5 working days (estimate). The dispatch clock starts at cleared payment.
